The novel inorganic matter tobacco thin sheet can get rid of the limitation to the supply of tobacco leaf raw materials; the problem of the current difficulty of insufficiency of tobacco leaf raw materials is solved; the defects of high water consumption, high power consumption and high steam consumption in the production of paper-making process sheet tobacco also can be avoided; and a new way is provided for adding modes of additives capable of being used for the cigarettes, such as insoluble essence and flavors and the like.

Description

An inorganic tobacco sheet and its preparation method

technical field

The invention belongs to the technical field of cigarettes, and in particular relates to an inorganic tobacco sheet and a preparation method thereof.

Background technique

Reconstituted tobacco originated in the 1950s, and its development has gone through three stages: roll pressing method-thick pulp method-papermaking method. According to different processing techniques, there are five main methods of manufacturing reconstituted tobacco leaves, namely, rolling method, papermaking method, thick pulp method, soaking method and spray layer method, among which the first three methods are the most commonly used in the world. Due to the strong human intervention in the production process of reconstituted tobacco leaves by papermaking method, the physical and mechanical properties and processability of reconstituted tobacco leaves by papermaking method are good, and while reducing the amount of tar released in cigarettes and harmful components in smoke, it can better maintain the smoking taste of cigarettes . At the same time, with the continuous deepening and advancement of the national bureau's "cigarette level" goal and task, and the completion and commissioning of a large-scale production line marked by 10,000 tons, papermaking reconstituted tobacco leaves are used in Chinese-style cigarettes to reduce tar and reduce harm, strengthen cigarette style features, and improve cigarette quality. Cigarette product quality stability and reduction of raw material consumption have played an important role and value. At present, the reconstituted tobacco leaf by papermaking method has been established as an important and indispensable raw material foundation for Chinese cigarettes. Therefore, the current manufacturing method of reconstituted tobacco leaf used in my country is papermaking method. However, due to the raw materials of reconstituted tobacco leaves (mainly tobacco leaf fragments), production costs, environmental protection and other issues, its production capacity and application in cigarettes are limited. The thick pulp method can avoid these defects well, especially the inorganic tobacco sheet can better solve the problem that the traditional thick pulp method sheet is broken on the cigarette production line. Indispensable component.

At present, the application of reconstituted tobacco leaves to achieve the effect of harm reduction and tar reduction is a commonly used and mature method. However, traditional reconstituted tobacco leaves rely on tobacco leaf materials such as tobacco stems, and require sufficient raw materials, and traditional reconstituted tobacco leaves generally bring about the side effect of increasing carbon monoxide in mainstream smoke. Therefore, the use of reconstituted tobacco leaves to achieve the purpose of "reducing harm and reducing coke" has certain limitations.

Therefore, the development and preparation of an inorganic tobacco sheet that is separated from tobacco leaf raw materials is not only conducive to solving the current plight of insufficient tobacco leaf raw materials, but also avoiding the defects of high water consumption, high power consumption and high steam consumption in the production of reconstituted tobacco leaves by papermaking methods, and is insoluble The addition of flavors and fragrances and other additives that can be used in cigarettes provides a new way.

Contents of the invention

The purpose of the present invention is to provide an inorganic tobacco sheet separated from tobacco leaf raw materials, solve the current plight of shortage of tobacco leaf raw materials, and provide a new way for adding additives such as insoluble flavors and fragrances that can be used in cigarettes.

The technical scheme that the present invention adopts is as follows:

A method for preparing an inorganic tobacco sheet, comprising the steps of:

Step (1), dissolving edible gum in water to form a stable colloidal solution, wherein the mass ratio of water to edible gum is 18.75-100:1;

Step (2), adding inorganic materials, smoke fillers and pigments to the colloidal solution obtained in step (1), and stirring continuously until the mixture is uniform, to obtain a colloidal suspension;

The inorganic material is a water-insoluble powder material, and no harmful substances will be produced after heating or burning; the mass ratio of the added amount of the inorganic material to the water added in step (1) is 1:7.5-15;

The smoke filling agent is a substance with good thermal mobility, or a latent aroma substance that can produce smoke aroma after being heated or burned;

The mass ratio of the added amount of the smoke filler to the water added in step (1) is 1:15-50;

The pigment is food pigment, and the mass ratio of the added amount to the water added in step (1) is 1:1500-7500;

In step (3), the colloidal suspension obtained in step (2) is produced on a thin sheet process line of thick slurry method to prepare inorganic tobacco sheet.

Further, it is preferred that the edible gum is sodium alginate, carrageenan or gum arabic.

Further, it is preferred that the inorganic material is an inorganic salt, non-heavy metal oxide or non-heavy metal hydroxide.

Further, preferably, the inorganic material is calcium carbonate, zinc phosphate, calcium oxide or aluminum hydroxide.

Further, it is preferred that the substance with better thermal mobility is propylene glycol, glycerin or tobacco flavor and fragrance.

Further, it is preferred that the flavor and fragrance for tobacco is rose essential oil or geraniol.

Further, it is preferred that the latent aroma substance is coffee powder or polysaccharide.

Further, it is preferred that the pigment is a natural pigment.

Further, it is preferred that the natural pigment is caramel pigment, tobacco extract or tea extract.

After the prepared inorganic tobacco sheet is shredded according to the required requirements, it is added into shredded cigarette tobacco for production. It can selectively reduce the harmful components in the cigarette smoke, increase the aroma of the smoke, increase the moisture content of the smoke, and improve the comfort of the smoke, and present the same color as shredded tobacco without affecting the appearance of the cigarette.

Compared with the prior art, the present invention has the beneficial effects of:

The present invention adopts inorganic materials as the composition matrix and adds the smoke filling agent as the combustion transfer material, which can selectively reduce the harmful components in the cigarette smoke, increase the aroma of the smoke, increase the moisture content of the smoke, and improve the comfort of the smoke , and after choosing to add a suitable pigment, it can make it present the same color as the shredded tobacco. Moreover, this new type of inorganic tobacco sheet can get rid of the restriction on the supply of tobacco leaf raw materials, solve the current plight of insufficient tobacco leaf raw materials, and can avoid the defects of high water consumption, high power consumption and high steam consumption in the production of reconstituted tobacco leaves by papermaking methods, and It provides a new way for the addition of additives such as insoluble flavors and fragrances that can be used in cigarettes.
